Zoloft help! Pleease.

[Anxiousbb]

So I was taking Paxil for the past 2 years at very low doses.. Weaned myself off, but after two weeks off it decided it wasn't the right time and went back to it due to reemerging anxiety and depression. When I reinstated it at a very low dose I got a bad reaction, I felt horrible increased anxiety, depression and suicidal ideation(for the first time in my life) and burning sensations on my scalp and hands. Went to a psychaitrist after a week because it was unbearable and I wasn't stabilizing he told me to immediately switch to Lexapro 20mg, took it after about an hour I felt severe jitters and nausea, I felt like I'd had 10 cups of coffee and vomited..and had stomach and liver pain.. I reduced my dose later on but still had terrible anxiety worse in the morning with doom feelings and panic attacks were up through the roof, I felt suicidal and was at the end of my rope with the physical and mental side effects. I felt so troubled because I wasn't this bad before messing up with the meds. I stayed on Lexapro for a total of 20 days but could not bear it any longer. Went to my old psychaitrist that prescribed Paxil initially and helped me. He said I shouldn't be feeling this way for this long and he switched me to 100mg Zoloft and pregabalin for the first two weeks. I had some hope and faith in this doctor as he had helped me before.. Initially I felt slightly better, Zoloft seemed to be easier on my body than Lexapro but I still woke up with shakey hands and burning sensations in my limbs coupled with doom feelings.. On days where my anxiety seemed to subside my depression felt horrible and unbearable..I sobbed for hours and the only thing I looked forward to was sleep.. I figured he started me on a high dose and should have titrated up a bit slower.. Reduced to 50mg still bad, then eventually to 25mg a day. Been on 25mg for ten days now and on Zoloft a total of 24 days. This last week I felt the side effects reducing, however I I've developed this bad fatigue and exhaustion and it scares me so much. It's like the only thing I can do is sleep and a day ago I slept on and off for 24 hours. I have no energy to talk to people or do anything.. Sleep has been my only comfort and solace these past two months of horror and utter hell!
What worries me now is that I developed some fatigue syndrome and worry that I will never lead a normal happy life again.. And worry that Zoloft will not help me, it's 3 weeks so far and only ten days on a stable 25mg after reduction. Is this reduced mental capacity and concentration and exhaustion due to Zoloft or due to the fact that I suffered two months of constant day and night anxiety attacks and panic and my body is drained???? Will it go away or is this permanent?! I wasn't a very energetic person before but at least I led a normal happy life.. And now I can't seem to shake off this depression and exhaustion.. Someone tell me it gets better.. I'm so afraid to have to switch meds again. I lived through hell I can't do it again.. Please help
