First, it is great that you are comfortable in coming and posting a lot here in the past. We may not be able to give you concrete solutions, but you will find that we will be supportive of you.
It is not unusual to move from depression to anxiety. I have had it happen to me. Now, I am not a med professional so this is just from me. When I come out of a depression episode, I feel quite good and wanting to get on with life but I get anxious because I start anticipating the future rather than living each day. So, I swing into anxiety. Now, you are going through several life experiences all at the same time and this can be overwhelming and add to the anxiety.
At 26, I can well understand that for all the reasons you listed, you are anxious about getting on with your life and this is not an unusual goal. Couple to that you identify with what you haven't got . . . no car, no permanent position, living with your parents. At the same time, I sense, and I could be wrong, that you might feel that you might be adding to your parents' financial condition. So, can you turn this around and see what you do have? From what I can tell, you are supporting to support your parents in terms meaning to them in the best way you can but it is discouraging when the choice is between giving your Mom something (cremation of the dogs) at the expense of your own needs. In other words, you are doing the best you can for everyone, but sometimes it does not seem enough or it does not seem appropriate because of the financial impact on you. I can see a bit of guilt going on here and, again, I might be wrong but if it is guilt, then you need to take steps to recognize that you have nothing to be guilty about. And, just maybe, you might be a bit better from an anxiety perspective if, when it is financially possible, that you go out on your own . . . you can still help your parents when you can, but you will be better able to control your finances if you do not feel guilty about living at home even if you are paying rent . . .
You have been getting a lot of hours as a temp even though things have slowed down, but those hours as a temp are experience that you would not otherwise have. Yes, being without a permanent position (I've been there several times) is scary and anxiety provoking because you don't know what the future might hold. I am assuming that you are applying at different locations, making your resume reflect your increasing skill sets, and selling yourself as a unique and desirable employee and that is a big accomplishment. I won't lie to you . . . finding a permanent position especially one with benefits is challenging in today's job market . . . but, you have experience and I sense you have a purpose and together with a bit of luck, you will succeed.
You also appear to have a very good grasp on recovery as a journey and not an event. It is difficult to stay hopeful because you know that the journey has speedbumps. But, you are not at the beginning of the process because you have knowledge of what the process is; you are at a new phase of the process but you have something that folks just experiencing anxiety for the first time do not have --- you have insights not only into the process and the journey, but you understand how you experience it. So, indeed, yes, stay hopeful because it is one day at a time and I think that despite the job / financial set back and your obvious desire to improve yourself so you can help your family, you have come forward on your journey.
As difficult as it is right now, focus on the positives that you have . . . no, don't ignore the challenges that you need to meet, but, at the same time don't sell yourself short . . . . and, please, come here as often as you wish and if it is even just to say hi, that is great but, if you feel comfortable with doing so, let us know how you are doing and if we can help, know that we will do our best . . .take care, kc
